FTTR (Fiber to the Room) is an all-optical networking technology that replaces traditional copper cables (e.g., Ethernet cables) with fiber optics, delivering gigabit or even 10-gigabit network coverage to every room in a home. It enables ultra-high-speed, low-latency, and highly stable whole-home connectivity. Below are the key features and applications of FTTR: 1. Core Technologies of FTTR All-fiber transmission: Extends fiber optics from the household entry point (FTTH) to each room, eliminating the bandwidth limitations of copper cables. Master-slave optical gateways: Master gateway: Connects to the ISP’s fiber, handling optical-electrical conversion and network management. Slave gateways: Deployed in individual rooms, connected to the master via fiber, providing Wi-Fi and wired access. P2MP/P2P architecture: Uses passive optical splitters (PON) or point-to-point fiber links for flexible scalabily.   2. Advantages Over Traditional Solutions Comparison FTTR Traditional FTTH + Ethernet/Wi-Fi Bandwidth Gigabit/10G to every room Limited by copper cables (e.g., Cat5e/Cat6) Latency Lower (fiber efficiency) Higher (signal attenuation/interference) Coverage Whole-home, stable signal Depends on router placement, dead zones possible Future-proofing Supports upgrades (e.g., 10G PON) Requires rewiring   3. Typical Use Cases Households: Large homes, villas, smart homes (high device concurrency). Businesses/Hotels: High-density connectivity, video conferencing, cloud办公 (cloud office). 4K/8K/VR: Ultra-high bandwidth and low-latency immersive experiences.   4. Deployment Challenges Higher cost: Fiber deployment and optical gateways are more expensive than traditional setups. Installation complexity: Requires professional fiber routing; older buildings may pose difficulties. Device compatibility: Some devices still rely on Ethernet or Wi-Fi from slave gateways.   5. Current Development Status ISP adoption: Carriers like China Mobile, Telecom, and Unicom are piloting FTTR with bundled service packages. Industry standards: Vendors like Huawei and ZTE are pushing standards (e.g., Huawei’s C-WAN architecture).   Conclusion FTTR is a key direction for next-gen home networks, especially for high-demand scenarios. As fiber costs decline and ecosystems mature, it may gradually replace traditional copper-based solutions. What we can do?

What is FTTC? – Fiber to the Cabinet Fiber to the cabinet is a connectivity technology that is based on a combination of fiber optic cable and copper cable. The fiber optic cable is in place from the local telephone exchange to a distribution point (commonly called a roadside cabinet), hence the name fiber to the cabinet. From this distribution point, a standard telephone line based on copper is then used to deliver the broadband connectivity. How does FTTC work? Basically, FTTC is a fiber optic connection from the switch to the cabinet that is shared between various people over copper telephone lines. Fiber optic connections are made from your nearest switch to the nearest “cabinet”. These cabinets are green boxes that you may see locally that are used to distribute the Internet to various people on the network. Alternative names for FTTC Some of the other common names people use when referring to FTTC include:●Super-Fast Broadband●Infinity●Fiber Broadband FTTC Speeds The speed of your FTTC connection is largely dependent on how close you are to the nearest cabinet and how many other people are sharing the connection. ●Downloading speedIn general, FTTC offers three different download variants, which are:80Mbps download (76Mbps maximum throughput)55Mbps download (52Mbps maximum throughput)40Mbps download (38Mbps maximum throughput) ●Uploading speedThe upload speed provided for FTTC is usually:20Mbps upload (80Mbps download)10Mbps upload (55Mbps or 40Mbps download)2Mbps upload (40Mbps download)There are no guaranteed download or upload speeds for FTTC connections, and performance will depend heavily on the amount of data used by others on the network and your distance from the cabinet. If you live within 100M of the cabinet and there are not too many other users on the network, then the above download and upload speeds are very achievable during off-peak hours. Otherwise, it’s worth checking your actual estimated speeds before signing any contracts. Benefits of FTTC ●Low PriceFTTC is one of the cheapest Internet connections available in China. It utilizes existing phone lines, keeps setup costs low, and has virtually no ongoing maintenance costs. The monthly rent is also very low. ●Faster than ADSL Since the connection between the cabinet and the switch is via fiber, the FTTC connection will give you faster speeds than an ADSL line. Drawbacks of FTTC●Fierce competitionWith many other users sharing the same connection, your download and upload speeds will fluctuate throughout the day, making it difficult to use in a business environment.●Slow speedsAlthough an FTTC connection is faster than ADSL, it is still very slow compared to leased fiber or wireless lines.●No SLAService Level Agreements guarantee uptime, fast service recovery and 24/7 monitoring of the connection. This is fairly common when viewing business Internet connections, but it is not available on FTTC connections.In summary, FTTC Broadband is a trusted universal Internet service. It is a hybrid broadband system that uses both fiber optic cables and traditional copper wires to provide high-speed Internet connectivity. FTTC broadband is faster and more reliable than traditional ADSL broadband, as well as a cost-effective solution to deploy. However, its limitations must be considered, for example, depending on distance and availability in different areas.HEAT SHRINKABLE SPLICE CLOSURE/SLEEVE/TUBE (RSBJ,RSBA, XAGA, VASS, SVAM)FIBER OPTIC SPLICE JOIN CLOSURE/BOXODF/PATCH PANELKINDS OF CABINETSCOMPLETE SOLUTION OF FTTx www.qhtele.comoverseas@qhtele.comChengDu QianHong Communication Co., LTDCHENGDU QIANHONG SCIENCE AND TECHNOLOGY CO., LTD

Fibre-to-the-home (FTTH) is a broadband network architecture that uses optical fibre to deliver high-speed Internet and other communications services directly to homes. This involves an Optical Line Terminal (OLT) at the central office, which drives an Optical Distribution Network (ODN) that routes signals to multiple homes using passive optical splitters along the way.   So how fibre-to-the-home is installed?   Ⅰ. Pre-burieded main cables Firstly, the construction team needs to dig a trench near the community to splice the feeder cable to the backbone fibre-optic cable. Ⅱ. Drop cable access to the cell Pull  feeder cable out of the ground or tube via a lead-through to access your plot or yard outside your house. Ⅲ. Splitting in splitter boxes in the cell Put the feeder cable into the splitter box in the cell and be split via PLC for multiple home use. Ⅳ. Fibre optic cable to subscriber access point Put the distribution cable into the storage box at your doorstep. Ⅴ. Fibre optic cable to the home Pulling the drop cable into the house through a through-wall connector or a traction cord Ⅵ. Indoor cabling Run the white or transparent cable from the living room all the way to the bedroom along the door frames, etc. in your house. Ⅶ. Networking Final step, extending your network to rooms such as the study and bedroom, via a router.Congrats on finishing your FTTH build!

Optical Fibers: The core component of FTTA is the optical fiber itself. Single – mode fibers are commonly used in FTTA deployments due to their ability to transmit optical signals over long distances with minimal attenuation. These fibers are designed to carry high – speed data, voice, and video signals from the base station to the antenna. For instance, in a large – scale 5G network deployment, kilometers of single – mode optical fibers are laid to connect multiple RRHs to their respective BBUs. Optical Transceivers: These are essential for the conversion of electrical signals to optical signals and vice versa. Transmitters at the BBU side convert electrical signals into optical signals suitable for transmission over the fiber. Receivers at the RRH end perform the reverse operation, converting the received optical signals back into electrical signals. High – performance optical transceivers are crucial for maintaining signal integrity and ensuring fast data transfer rates. Remote Radio Heads (RRHs): The RRH is located near the antenna and is responsible for amplifying the electrical signals received from the optical fiber and transmitting them wirelessly. It also performs functions such as signal modulation and demodulation. RRHs are designed to be compact and energy – efficient, enabling easy installation at various antenna sites. Base – Band Units (BBUs): BBUs are the central processing units of the base station. They handle the digital signal processing tasks, such as encoding, decoding, and managing the communication with the core network. In a FTTA – based network, BBUs are connected to multiple RRHs through optical fibers, allowing for centralized control and management of the wireless network. Infrastructure Installation: The installation of FTTA infrastructure requires careful planning. Fiber optic cables need to be laid, either underground or overhead, depending on the terrain and local regulations. In urban areas, underground fiber installation is often preferred to avoid interference and maintain the aesthetics of the cityscape. In addition, proper protection of the fiber cables is necessary to prevent damage from environmental factors, construction activities, or other potential hazards. The FTTA infrastructure also needs to be integrated with the existing wireless network infrastructure, including the core network, power supply systems, and other supporting equipment. This integration requires compatibility testing and seamless coordination to ensure the smooth operation of the entire wireless communication network.HEAT SHRINKABLE SPLICE CLOSURE/SLEEVE/TUBE (RSBJ,RSBA, XAGA, VASS, SVAM)FIBER SPLICE JOIN CLOSURE/BOXODF/PATCH PANELKINDS OF CABINETSCOMPLETE SOLUTION OF FTTx http：//www.qhtele.com.cn oversea@zcloudtech.net ChengDu QianHong Communication Co., LTD CHENGDU QIANHONG SCIENCE AND TECHNOLOGY CO., LTD
